Abstract
A thermoplastic elastomer composition for crosslinked foam and the manufacturing method thereof are provided. The thermoplastic elastomer composition comprising (A) an ethylene-based copolymer; (B) a first copolymer; (C) a second copolymer, wherein the component (B) and (C) are copolymers comprising a vinyl aromatic monomer and a conjugated diene monomer, the first copolymer having a conjugated diene hydrogenation rate of at least 80% and the second copolymer having a conjugated diene hydrogenation rate of no more than 10%; (D) an organic peroxide; and (E) a foaming agent, wherein a mass ratio (A/(B+C)) of the component (A) to a combination of the component (B) and the component (C) is 95/5 to 5/95; and a mass ratio (B/C) of the component (B) to the component (C) is 9/1 to 1/9. A crosslinked foam made from the composition and the manufacturing method thereof are also provided.
